    Inaccuracies.
    For the last km of my last run I really picked up the pace. You can see exactly where I changed pace but the pace dropped down.... My theory is that the Sensor and Sportband measure when your foot and arm move apart. One would assume that to run faster you speed the foot pace up but alot of my speed comes from lengthening the stride this is where the sensor thinks I have slowed down.

    Another way of testing this is to run up hill (short strides), and then down hill (longer strides). Downhill you would assume the pace on the chart (on the nike plus website) to pick up. In fact it does the opposite.

    Anyone else notice this?

    ....do I make any sense?

    • yeah... sorta... I get huge drops in every run...as bad as half of my speed and it sometimes stays like that for 2 mins...VectorMasked
    • I really don't know why it happens when there's no change in surface speed or stride.VectorMasked
